Towards Browsing Distant Metadata Using Semantic Signatures
In this document, we describe a light-weighted ontology mediation method that allows users to send semantic queries to distant data repositories to browse for learning object metadata. In a collaborative E-learning community, member data repositories might use different ontologies to control a set of vocabularies describing topics in learning resources. This could hinder the search of learning resources based on local ontological concepts. With the use of WordNet, we develop a toolkit that indexes ontological concepts with WordNet senses for semantic browsing in order to integrate information in a distributed learning community. The effectiveness of the toolkit was validated with real-world data in a specific domain, namely Elearning metadata.
